Baseline investigation on plasticizers, bisphenol A
The method detection limit (MDL) ranged between 0.09 and 0.24 ng/g for plasticizers, 0.07–0.61 ng/g for PAHs and 0.06 ng/g for BPA. With each set of five samples, one spiked procedural and solvent blank were run to check for background contamination, peak identification and quantification.

Electronic waste (e-waste) has emerged as a global environmental problem because of its massive production volume and un-structured management policy. Since the rate of e-waste accumulation is startling and the combinatorial effects of toxicants are complex, we have investigated six phthalic acid esters (PAEs), bis (2-ethylhexyl) adipate (DEHA)), bisphenol A (BPA), sixteen polycyclic aromatic

- Are industrial sites a major source of plasticizers?
- Industrial sites contributed to one-third of the total plasticizers found in this study with major concentrations of DEHP, BBP, DEHA and DnOP. Industrial emission is an important source of plasticizers and can release up to 114,000 kg/year of DEHP alone (Sidhu et al. 2005).
- Why are BPA and plasticizers in riverine sediments high?
- High average concentrations of BPA and plasticizers in riverine sediments from both the rivers might have resulted from the low water flows thereby reducing the dilution factor. The concentrations of plasticizers and BPA in sediments justify the need to restrict the discharge of wastewater into the two rivers.
- What is the global use of plasticizers?
- In 2015, the global use of plasticizers was 8.4 million tons (MT), and bis (2-ethylhexyl) phthalate (DEHP) represented 37% of the global plasticizer market. Additives like bisphenol A (BPA) is used up to 3% by weight mostly in polycarbonate (71%) and epoxy resins (29%) (Huang et al. 2012).
- How many plasticizers and BPA are in Chennai River?
- This study reports the distribution of ∑ 7 plasticizers (6 PAEs and DEHA) and BPA along two major rivers flowing through Chennai city. Elevated levels of BPA and plasticizers were mainly attributed to the high load of industrial and domestic wastewater activities in addition to the burning of plastic waste along both the rivers.
- How are plasticizers and BPA detected?
- Plasticizers and BPA were detected and quantified using an Agilent 7890B gas chromatography coupled to a 5977A mass spectrometer equipped with an HP-5MS column (30 m × 0.25mmi.d. × 0.25 μm film thickness). The flow rate of the carrier gas (He, 99.99% purity) was kept constant at 1.5 mL/min.
- Do plasticizers and BPA contaminate sediments in Chennai city?
- The concentrations of plasticizers and BPA in sediments justify the need to restrict the discharge of wastewater into the two rivers. However, further studies to assess the sediments quality in Chennai city are necessary.
